okay this sounds stupid, and the answer is probably simple, on my 2000 cr-v after my throttle body, attached to and ontop of my intake manifold is a big hollow square-ish pice of aluminum. is this where all the fumes from my crank case evaporates to? thats the only thing i can think of. i removed it and could see stright down into my intake manifold is it okay to remove this and cap the hole? and if so would i reap any benifits?
